Who had the bigger impact on Britain vikings or Anglo Saxons?

Vikings had an impact mainly on what is now Scotland and Ireland; their influence on England and Wales was limited mainly to the east and southeast of England and, after the pogrom which killed most able-bodied Vikings, virtually non-existent. The Anglo-Saxons greatly influenced England causing all natives to adopt their ways which lasted longer than the impact of the Romans. Except for the short-lived invasion of Angle Northumbria into southern Alba, (Scotland), the Anglo-Saxons main influence would be by trade with the other British Isles.
